December 12, 2025 -- Proverbs 12:12-14 -- The zombie-parasite of sin and its antidote
/People loved by the Father, in the Spirit's power: Sh'ma ~hear and obey Jesus!
Whoever is wicked covets the spoils of evildoers,
but the root of the righteous bears fruit.
An evil man is ensnared by the transgression of his lips,
but the righteous escapes from trouble.
From the fruit of his mouth a man is satisfied with good,
and the work of a man’s hand comes back to him. Proverbs 12:12-14 ESV
Have you ever heard of zombie mice? Sound like the plot of a “B” movie, doesn’t it? A mouse infected with toxoplasma gondii has a parasite that radically affects the behavior of the mouse. This toxoplasma gondii works on the brain of the mouse such that it no longer has a fear of cats. When a cat eats the numbed, fearless, infected mouse, the life cycle of the parasite continues in the cat. Does that ever sound like sin!
Look at the recklessness that sin evokes from the man or woman infected by it. The wicked man (one so infected by the parasitic machinations of sin) longs for, studies, constantly thinks about whatever it is that evildoers have. They want what they don’t have. They crave it. The more they focus on it, the more alluring it is. The more the parasite of sin lures them to the jaws of self-destruction and death.
The perverted longing of the heart, infected by the parasite of embedded sin, will keep that sinner babbling on about the very thing that is killing him. The people all around him can see the death it is bringing, the reckless behavior that accompanies it, but obliviously, he talks on, mocks on, and walks right to his death.
Sin, as defined by Tim Keller, (who in turn got it from Romans 1) is disordered worship. But it doesn’t stop there. When someone is captivated by sin, staring at it, longingly considering it, such delinquent behavior evokes more delinquent behavior. Sin generates more sin as its parasitic nature means it will multiply in its host and lead the host to death.
The antidote is found in our reading in Proverbs. A righteous man and a righteous woman are those, healed in Christ, who know the holiness of God and express it in daily life. They had the infectious parasite of sin raging in them. But the Spirit of God restrained the full extent of their sin. The Spirit of God brought them to the point of self-awareness, so they realized their utter neediness and helplessness. The Father grafted them into Jesus Christ—the root and true vine of all holiness. They were not naturally fruitful. They were not naturally able to do any good work. It was and is the life-giving, hope-restoring, fruit-bearing life of Jesus working in them that broke the cycle of sin and its parasitic influence.
When a righteous man sees a sinner, he realizes the stupefying effects it has on its hosts, and he prays even more earnestly for the sinner. When a righteous woman sees an evildoer, she has compassion, knowing herself how controlling and tyrannical its effects are on its host. Therefore, the righteous man and the righteous woman do not join in wickedness, but escape trouble through greater union with Jesus and Spirit-fueled love for the Father, Who effected this rescue. Christians are not better than zombie sinners, they are grateful hosts of the Spirit of Jesus Who leads them in good and godly works.
Our Father in heaven, thank You for rescuing us from the parasitic, death-inducing, tyranny of sin. Blessed be Your Name. Thank You, Jesus, for the inestimable love which You have demonstrated toward us at Your incarnation, and by Your life, suffering, crucifixion, death, resurrection, session to the Father’s right hand and now Your rule in glory. Holy Spirit, thank You for maintaining our connection to Jesus through in-grafting, and enabling the healing life which flows from the root of Jesus’ righteousness to inoculate us against every sin and curse so that we are satisfied with good. Amen.
